AsyncBuilder.Bind<'T,'U> Method (F#)

  • Article

Implements let! in asynchronous computations.

Namespace/Module Path: Microsoft.FSharp.Control

Assembly: FSharp.Core (in FSharp.Core.dll)

// Signature:
member this.Bind : Async<'T> * ('T -> Async<'U>) -> Async<'U>

// Usage:
asyncBuilder.Bind (computation, binder)

Parameters

  • computation
    Type: Async<'T>

    The computation to provide an unbound result.

  • binder
    Type: 'T -> Async<'U>

    The function to bind the result of computation.

Return Value

An asynchronous computation that performs a monadic bind on the result of computation.

Remarks

Creates an asynchronous computation that runs computation, and when the computation generates a result, passes the result to binder that binds the result of the computation to a value.

A cancellation check is performed when the computation is executed. The existence of this method permits the use of let! in the async { ... } computation expression syntax.
